Description

Изобретение относится к медицинской технике, а именно, к хирургическим дренирующим устройствам, и может быть использовано для аспирации из полостей организма, в том числе с промыванием.The invention relates to medical equipment, namely to surgical drainage devices, and can be used for aspiration from body cavities, including washing.

Известен дренаж, включающий зла- > стичную трубку с диаметральной продольной перегородкой, образующей засасывающий с боковыми отверстиями канал и аспирационный канал, и наконечник на рабочей дистальной части трубки [1].Known drainage, including an evil-> ostomy tube with a diametrical longitudinal septum, forming a suction channel and suction channel with side openings, and a tip on the working distal part of the tube [1].

Однако наличие жесткого наконечника исключает возможность использования известного дренажа для длительной аспирации из брюшной полости, а также из других полостей организма, так как возникает возможность обраэования пролежней. Кроме того, очень ' 20 трудно очистить внутреннюю полость такого наконечника после употребления дренажа. Перечисленные недостатки приводят к затягиванию сроков лечения гнойных заболеваний при исполь-25 зовании известного дренажа.However, the presence of a rigid tip excludes the possibility of using the known drainage for long-term aspiration from the abdominal cavity, as well as from other cavities of the body, since there is the possibility of forming pressure ulcers. In addition, it is very difficult to clean the internal cavity of such a tip after using drainage. These shortcomings lead to a delay in the treatment of purulent diseases when using known drainage.

Цель изобретения - сокращение сроков лечения гнойных заболеваний.The purpose of the invention is the reduction of the treatment of purulent diseases.

Поставленная цель достигается тем, что в дренаже, содержащем эластичную 30 совыми,, могут иметь круглое или сегментное сечение. Трубка 7 служит для соединения засасывающего канала 3 с атмосферным воздухом и с промывной (лекарственной) капельницей, а трубка 8 служит для соединения аспира- _ ционного канала 5 с банкой-Сборником стандартного аспирационного (отсасывающего) устройства.This goal is achieved by the fact that in the drainage containing elastic 30 owls, they can have a round or segment section. Tube 7 serves to connect the suction channel 3 with atmospheric air and with a wash (drug) dropper, and tube 8 serves to connect the suction channel 5 with the collection can of a standard suction (suction) device.

Дренаж работает следующим образом.Drainage works as follows.

Дренаж устанавливают в просвете...Drainage is installed in the lumen ...

полого органа желудочно-кишечного* тракта при подключении аспирационного канала 5 через трубку 8 к работающему аспирационному (отсасывающему) устройству, происходит принудительный засос атмосферного воздуха 15 через трубку 7 в засасывающий канал и через просвет ’’а* * в аспирационный канал 5. Такое движение потока воздуха создает инжекционный эффект, обеспечивающий засасывание жидкого 20 содержимого из дренируемой полости внутрь дренажа через боковые отверстия и торцевое отверстие наконечника 6. Атмосферный воздух и жидкое содержимое поступают из засасывающего канала 3 через просвет ¹'а'' в аспирационный канал 5 и далее в банку-сборник. Таким образом, отсос жидкого содержимого из дренируемой полости производится по аспирационному каналу 5. Соответственно, протекание жидкого содержимого из канала 3 в канал и, в целом, все дренирование осуществляется принудительно, под действием разряжения, создаваемого стандартным аспирационным устройством. Кроме того, наличие однонаправлен ного потока воздуха способствует поступлению внутрь дренажа промывной жидкости, которая облегчает продвижение густого содержимого. Постоянное соединение внутреннего объема дренажа с атмосферным воздухом снижает опасность присасывания прилежащих кишечных петель к отверстиям дренажа, а выбранный размер просвета ’’а'’ в диаметральной перегородке исключает закупоривание дренажа при движении отсасываемых частиц.a hollow organ of the gastrointestinal * tract when connecting the suction channel 5 through the tube 8 to a working suction (suction) device, there is a forced suction of atmospheric air 15 through the tube 7 into the suction channel and through the lumen `` a * * into the suction channel 5. This movement the air flow creates an injection effect, ensuring the suction of the liquid 20 contents from the drained cavity into the drainage through the side openings and the end hole of the tip 6. Atmospheric air and liquid content Payuta of sucking duct 3 through the lumen of ¹ 'and''in the suction channel 5 and further into the collecting bank. Thus, the suction of the liquid contents from the drained cavity is carried out through the suction channel 5. Accordingly, the flow of the liquid contents from the channel 3 into the channel and, in general, all drainage is forced, under the influence of a vacuum created by a standard suction device. In addition, the presence of a unidirectional air flow facilitates the flow of washing liquid into the drainage, which facilitates the promotion of thick contents. The constant connection of the internal volume of the drainage with atmospheric air reduces the risk of suction of the adjacent intestinal loops to the drainage holes, and the selected lumen size `` a '' in the diametric partition prevents clogging of the drainage when the suction particles move.

Таким образом, конструкция дренажа позволяет использовать его для длительной аспирации из полостей организма, способствуя сокращению сроков лечения гнойных заболеваний.Thus, the design of the drainage allows it to be used for long-term aspiration from the body cavities, helping to reduce the treatment time for purulent diseases.

Claims

The invention relates to a medical CKoft technique, namely, to surgical drainage devices, and can be used for aspiration from body cavities, including with washing. A drainage is known, which includes an elastic tube with a diametral longitudinal partition, forming a suction channel and an aspiration channel with side holes, and a tip on the working distal part of tube 1. However, the presence of a rigid tip eliminates the possibility of using known drainage for long aspiration from the abdominal cavity also from other cavities of the body as the possibility of formation of pressure sores arises. In addition, it is very difficult to clean the internal cavity of such a tip after consuming drainage. These deficiencies lead to the tightening of the terms of treatment of purulent diseases when using the known drainage. The purpose of the invention is to reduce the duration of treatment of purulent diseases. The goal is achieved by the fact that in a drainage containing an elastic tube with a diametrical longitudinal partition forming two channels, one of the KOTOpfcix is made with a number of side holes and a tip at the working end, the partition is at least half the tube diameter and the tip is made hollow from a soft material, mainly silica-organic rubber. FIG. 1 shows a drainage with a partial section; in fig. 2 is a section A-A in FIG. 1. Drenches1zh consists of an elastic tube 1 with a longitudinal diametrical partition 2, forming a suction channel 3 with side openings 4 and an aspiration channel 5, and a tip 6 at the distal working end of the tube. The longitudinal partition 2 is not brought to the base of the tip 6 by a lumen value a equal to at least half the diameter d Tpy6j H 1. The tip 6 is made of a hollow soft material, for example, of silicone rubber. The non-working end of the drainage is equipped with two adjustable thin-walled tubes 7 and 8, which can be metal, glass or plastic, can have a circular or segmental section. The tube 7 serves to connect the suction channel 3 with atmospheric air and with the washing (drug) dropper, and the tube 8 serves to connect the suction channel 5 with the can-Collection of the standard suction device. Drainage works as follows. Drainage is installed in the lumen of the hollow organ of the gastrointestinal tract when the aspiration channel 5 is connected through the tube 8 to the working aspiration (suction) device. Such a movement of air flow creates an injection effect, which sucks the liquid contents from the drainable cavity into the drainage through the side openings 4 and the end opening tip 6 Atmospheric air and liquid contents flow from the suction channel 3 through the lumen into the aspiration channel 5 and further into the collection canister. Thus, the suction of the liquid contents from the drainage cavity is performed through the aspiration channel 5. Accordingly, the flow of the liquid contents from the channel 3 into the channel 5 and, in general, all the drainage is forced, under the action of the discharge created by the standard aspiration device. In addition, the presence of a unidirectional air flow contributes to the inward drainage of the washing liquid, which facilitates the advancement of the thick contents. The constant connection of the internal volume of drainage with atmospheric air reduces the risk of sucking adjacent intestinal loops to the drainage holes, and the selected size of the lumen and in the diametrical septum eliminates clogging of the drainage during the movement of suction particles. Thus, the drainage design allows it to be used for long-term aspiration from the body cavities, helping to reduce the duration of treatment of purulent diseases. DETAILED DESCRIPTION OF THE INVENTION Drainage comprising an elastic tube with a diametral longitudinal partition forming two channels, one of which is made with a number of side holes, and a tip at the working end, characterized in that in order to shorten the treatment of purulent diseases, the partition is separated from a distance equal to not less than half the diameter of the tube, and the tip is made hollow from a soft material, mainly silicone rubber.
